Why code is not being executed?

I have the following method in a class that extends WebView

- (void)webViewDidStartLoad:(UIWebView *)webView
{
    NSLog(@"WEBVIEW - Start Load");

    static BOOL isFirstLaunch = YES;

    if (isFirstLaunch) {
        isFirstLaunch = NO;

    } else {
        [webView stringByEvaluatingJavaScriptFromString:@"localStorage.states = '[{},{\"name\":\"Dashboard\"}]'"];
    }
      // webView connected
    webviewTimeout = [NSTimer scheduledTimerWithTimeInterval:kWebViewLoadTimeOut target:self selector:@selector(webViewTimeout) userInfo:nil repeats:NO];
}

the static declaration plus the if else is jumped when program is executing. I notice this when in Xcode debugger. I can't see anything wrong with my code. I though it could be due to static BOOL variable declaration inside the method, I declared it out of any blocks in the .m file. but the if else still not being execute. I also tried to put the code in a ViewController class before loading my WebView, but the code mentioned still not being executed. What I'm missing here?

To be clearer: I notice that code is not being executed with Xcode Debugger. I put a breakpoint in the method beginning ,in NSLog, if I put any breakpoint in any part that is inside if else or in the static variable declaration, seems to ignore it, and no break is done.

Thanks in advance.

Compiler optimizations can sometimes confuse the debugger. They can rearrange instructions or even remove code. Turning them off can make it easier to step through the code.

Are you sure you have done the following:

// set yourself as the delegate
webView.delegate = self;

// begin loading
[webView loadRequest:[NSURLRequest requestWithURL:@"http://www.someURLHere.com"]];
